This is how QPlatformGLContext also makes it possible to use the QtOpenGL module - withhout using QGLWidget. When using QGLContext::currentContext(), it will ask - QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned, - which maps to the QPlatformGLContext. -*/ - -/*! \fn void QPlatformGLContext::swapBuffers() - Reimplement in subclass to native swap buffers calls -*/ - -/*! \fn void *QPlatformGLContext::getProcAddress(const QString &procName) - Reimplement in subclass to native getProcAddr calls. - - Note: its convenient to use qPrintable(const QString &str) to get the const char * pointer -*/ - -/*! \fn QPlatformWindowFormat QPlatformGLContext::platformWindowFormat() const - QWidget has the function qplatformWindowFormat().
